There's something wrong. Shouldn't it bekuruman said:There is nothing specific about this. Just put everything that depends on double prime under the integral sign that has ##dV''## and everything that depends only on prime under the integral sign that has ##dV'##. You do the double prime integral first and get a function of ##r'## and ##r##. Next you do the integral over primed variables and you get a function of ##r## only which will be an expression for ##Z(r)##.
It's like $$\int \int f(x,y)~g(x)~dx~dy=\int g(y)dy\int f(x,y)dx$$except with primes and double primes instead of ##x## and ##y##.
To get the second line of an equation from the first one, you can use various methods such as combining like terms, factoring, or using the distributive property. It ultimately depends on the specific equation and what you are trying to solve for.
Getting the second line of an equation allows you to simplify and rearrange the equation in a way that makes it easier to solve for the desired variable or to better understand the relationship between the different terms.
Sure, let's say we have the equation 2x + 4 = 10. To get the second line, we can subtract 4 from both sides to isolate the variable: 2x = 6. Then, we can divide both sides by 2 to solve for x: x = 3. The second line of this equation would be x = 3.
Yes, it is important to maintain the equality of the equation by performing the same operations on both sides. This means that whatever you do to one side, you must do to the other. Additionally, you should always aim to simplify the equation as much as possible.
Yes, simplifying and rearranging equations is a common practice in solving real-world problems in various fields such as physics, engineering, and economics. It allows us to better understand and manipulate the relationships between different variables in a given situation.
